Flotation machines are new products developed by our company, according to the decades of manufacturing experience. And it adopts forward curved tank and double impellers, equips with honeycomb duct. Therefore, the slurry in the tank will cycle upward and downward in a fixed flow manner, which is helpful to the suspension of those coarse particles. Air and slurry are naturally sucked without need for foam pump. Besides, flotation concentrator is widely applicable for coarese separation, fine separator and reverse flotation of nonferrous metals like copper, lead, zinc,nickel and molybdenum as well as ferrous metal and non-metallic minerals.However, in the flotation process, the hazards of overdose are often easily overlooked. Practical experience has shown that the flotation index declined, many cases is caused by flotation overdose. Overdose of cell flotation has the collector of excessive harm:1. excess collectors will further selection and mixing of foam concentrates concentrates separation difficult. In this case , the scene is often taken to be more modifiers way to remedy. Due to add more modifier, the mine contains an overdose of returned process, creating a vicious cycle . Causing confusion flotation separator process, reducing the flotation index. In addition, due to the excessive collector, inhibitor dosage should be increased, for example, xanthate excess inhibitors also increase the amount of cyanide, which is not only a waste of pharmacy , Pharmacy toxic tailings also allows content increased, causing public nuisance;2. superfluous collector may make minerals floating decrease. For example, excess fatty acids collectors make oxidized ore floatability reduce. It is due to collector on the mineral surface form multilayer adsorption reverse layers, the polar group outward, making mineral surface hydrophilic.3. selective flotation process of destruction. Practice has proved that a lot of testing and production, when collector dosage over a certain range, concentrate grade will be significantly decreased. Even recovery rate has a slight increase, it also do more harm than good;4. excess collectors will form large amounts of foam and make concentrate and tailings is not easy dehydration, bring difficulty for concentration and filtration.Henan Fote Heavy Machinery Co., Ltd. is a professional ore processing equipment manufacturer, mainly producing ball grinding mill, spiral chute separation, classifier, magnetic drum separation and so on.
